Subject Re: Query on Seed node
Date Mon, 03 Feb 2014 11:46:00 GMT
I'm guessing its just a coincident.. As far as I know, seeds have nothing
to do with where the data should be located.
I think there could be couple of reasons why you wouldn't see SSTables on a
specific column family folder, these are some of them:
- You're using a few distinct keys which non of them should be on that seed
- Node hasn't flushed yet.. You can use nodetool flush to try and flush
memtables manually.
- You're using manual token assignment and you didn't not assign them well.
